There is no need to "block the application". Use parallism. >My next idea is to just modify the application, and drop (with the >link() syscall) the message directly to postfix's queue directory, >and hopefully qmgr or something notices that "aha! I've got a new >message to deliver." In that case, you are on your own, with zero support. Translation: unlike the supported SMTP and sendmail iinterfaces that are maintained until eternity, your direct-to-queue submission method will break without any warning as Postfix evolves. Wietse
